An independent researcher reporting at the annual meeting of the American Society of Cataract and Refractive Surgery (ASCRS) finds that "Custom" or Wavefront-guided LASIK produces superior vision quality compared to traditional LASIK eye surgery. "While conventional LASIK is good, we're finding that wavefront guided LASIK yields sharper and higher quality vision, and higher patient satisfaction compared to conventional LASIK.
The improvement will likely be most apparent when driving at night," said US Navy Captain Steve Schallhorn, MD, the Director of Cornea and Refractive Surgery at the Navy Medical Center, San Diego.
We are finding that custom LASIK, without the use of glasses, is giving many patients the ability to see as well or better than they could see with glasses before surgery," he said. Schallhorn is part of a Navy program providing LASIK to Navy and Marine Corps personnel. "Refractive [LASIK] surgery plays a vital role in the military," he said. "By reducing dependence on glasses and contact lenses in active duty personnel, it enhances combat readiness and improves performance.
It also expands the applicant pool to talented young men and women for a variety of Navy programs." "Most significant," said Schallhorn, "is the improved quality of vision with the wavefront-guided procedure, fewer problems with halos and glare, better night vision, and higher patient satisfaction based on a detailed patient questionnaire."
Schallhorn's early findings compared the results the Navy Medical Center obtained in patients having conventional LASIK versus custom LASIK. With conventional LASIK 88 percent of 908 patients achieved 20/20 or better as tested six months after the procedure. By comparison 97 percent of 34 patients using the wavefront-guided LASIK achieved 20/20 or better.
Similarly, 85 percent of patients of wavefront-guided LASIK had 20/16 vision versus 69 percent of conventional LASIK patients six months following their procedures.
Schallhorn also noted that 30 percent of conventional LASIK patients reported an increase in night driving halo symptoms compared to no patients in the wavefront guided LASIK group.
After three months the majority of night halo problems abated for the conventional LASIK group. Conventional LASIK eye surgery has been around since 1995, but wavefront- guided LASIK has been widely available for only about a year and a half.
